I for one get many a strange look in my university library because I sit around boxing chunks of text for no apparent reason. Or spamming through my usual hotkeys in the correct order to "warm up for when I get home"
On a plus note though, I've noticed my guitar playing got a bit better due to the increased finger interdependence I got from playing a lot which was cool. My friends and I also can now speak exclusively using Starcraft analogies out when we're at bars, especially useful for pointing out hot chicks or particularly amusing looking fellows from afar without them realising. "She looks like you'll need a long-macro game to win" is a personal favourite of mine,
I'm sure some of you guys have tales that can easily trump my relatively poor anecdotes.
